Vintage USN Enlisted Tie Bar Clip

Preowned, Vintage, USN Enlisted Tie Clip, silver tone that shows wear to finish on the far left side opposite the USN symbol. It looks like a shadow line at the bend of the clip, but I believe it is actually scuffing from placing face down. Please see pictures and video to aid in description and for signs of age and wear. Quite sure this is Vintage early to mid 1970’s and is in really amazing vintage condition.
